I am looking for a way of warning users when they are logged in on more than one machine. I don't need them to be logged off automatically, jujst sent a netmsg telling them that they are already logged on at <machinename>
However, I haven't used net messages since the days on NT4, and I think the service that runs them on XP (we run a50-node XPSP2 network with WS2k3 domain) is stopped by default after Service Pack 2.
Could I do this using a batch file to check if a user is logged on?
Any suggestions appreciated
